... Tulln was known as Comagena
It was winter in the 1st c AD. Roman troops were stationed along the Danube. Armed cavalry troops patrolled the northern border of the Roman Empire. It was high time to build a defense installation for protection. The ideal site was soon found. Fort Comagena sprung up overnight. And with it came the first foundation walls in Tulln. A city with a history 2000 years old.
